Thanks for the swift response.
Well - I'll just keep an eye on it until my confidence increases - I'm just a paranoid sort of guy.
Do you have any idea how I can run it automatically? I've read that
"SuperDuper! does not have to be running for a schedule backup to
take place, but the user who scheduled it does have to be logged in,
with their account in front (if Fast User Switching is active), and the
screen must be unlocked."
I'm planning to log my mac mini away in a data centre which would theoretically allow anyone to walk up to it and start using it if it's in the state described in the help.
Any work arounds for running on the command line or similar?
Thanks again,
Simon
